*Relapse frequency reduction was significantly greater in the Betaferon than in the Avonex group at six months (p<0.001), 12 and 18 months (p = 0.01), and 24 months (p = 0.02). The reduction was calculated on the actual basal relapse frequency in the patient subgroups at each time interval.
No significant difference was found between Betaferon and Avonex groups in the proportion of relapse-free patients.
